+
+HOW TO STARTUP WITH A NEW ACTIVITY MODULE
+=========================================
+
+The following steps should get you up and running with
+this module template code.
+
+As you are able to read this file, you have probably managed to get this
+source code from either the CVS repository or from the zip archive. Well done!
+
+Read this README file.
+
+Make sure you have read this file :-)
+
+Rename the NEWMODULE folder into a lower case name of your module. Make sure
+your name is not used by any standard or contributed modules (see
+http://cvs.moodle.org/contrib/plugins/mod/ for the list of currently
+contributed modules).  
+
+Edit all the files in this directory and its subdirectories and change all the
+instances of string "print" to your new module name (eg "widget").
+   
+Rename the file lang/en_utf8/print.php to widget.php or whatever your
+module name is.
+
+Place the widget folder into the /mod folder of your development moodle
+directory.
+
+Go to http://localhost/your/moodle/admin/xmldb/ directory. Try to not to visit
+the main admin page (Notifications) so the module is not installed yet.  If it
+gets installed accidentaly, uninstall it from the database via Manage
+activities admin page. You will probably uninstall and reinstall the module
+quite often during the early stages of the development.
+
+In XMLDB editor, add all tables, fields and statements needed to implement the
+module features. See http://docs.moodle.org/en/Development:Using_XMLDB for
+more information. Do not forget to use the [Save] link at the XMLDB main page
+so the changes are written into install.xml file. If the link is not active,
+the web server process (eg. apache user) does not have permission to write
+into mod/widget/db/install.xml file
+
+Visit the admin Notifications page (admin/index.php). The module tables should
+get installed.
+
+You can go to Modules > Activities in the Site Administration block. You
+should find that this print has been added to the list of recognized
+modules.  
+
+You may now proceed to run your own code in an attempt to develop for moodle.
+Good luck with that. For help with developing code for moodle, visit the
+"Activity modules" developers forum in the online course called "Using Moodle"
+at http://moodle.org.
+
+
+What to do next
+---------------
+
+Go through the lib.php, index.php and view.php files.
+
+You will probably want to add some capabilities regarding your module. Look at
+db/access.php. Note that you have to increase the version number defined in
+version.php to let Moodle update the capabilities information.
+
+If you do any change to the database structure (adding a field, changing the
+field definition etc.) use XMLDB editor again. Use the PHP code generated by
+XMLDB and push it into db/upgrade.php. Save the change into install.xml (for
+fresh installations), increase the version number and go to admin/index.php
+again. During upgrade, Moodle calls a function in db/upgrade.php to perform
+the DB changes.

+// Capability definitions for the assignment module.
+//
+// The capabilities are loaded into the database table when the module is
+// installed or updated. Whenever the capability definitions are updated,
+// the module version number should be bumped up.
+//
+// The system has four possible values for a capability:
+// CAP_ALLOW, CAP_PREVENT, CAP_PROHIBIT, and inherit (not set).
+//
+//
+// CAPABILITY NAMING CONVENTION
+//
+// It is important that capability names are unique. The naming convention
+// for capabilities that are specific to modules and blocks is as follows:
+//   [mod/block]/<component_name>:<capabilityname>
+//
+// component_name should be the same as the directory name of the mod or block.
+//
+// Core moodle capabilities are defined thus:
+//    moodle/<capabilityclass>:<capabilityname>
+//
+// Examples: mod/forum:viewpost
+//           block/recent_activity:view
+//           moodle/site:deleteuser
+//
+// The variable name for the capability definitions array follows the format
+//   $<componenttype>_<component_name>_capabilities
+//
+// For the core capabilities, the variable is $moodle_capabilities.
